SportsStore是《精通ASP.NET MVC3框架(第三版)》中演示的MVC项目，在该项目中涵盖了MVC的众多方面，包括：使用DI容器、URL优化、导航、分页、购物车、订单、产品管理、图像上传......是不错的MVC实践项目，但该项目不是放在多层框架下开发的，离真实项目还有一段距离。本系列将尝试在多层框架下实现SportsStore项目，并用自己的方式实现一些功能。
本篇为系列第七篇，包括：
■ 9、实现订单提交
9、实现订单提交
首先在购物车显示页面Cart/Index.cshtml中，添加结账按钮：
@model MySportsStore.WebUI.Models.CartIndexViewModel @{ ViewBag.Title = "Index"; Layout = "~/Views/Shared/_Layout.cshtml"; } <table width="50%" align="left"> <thead> <tr> <th align="left">产品名称</th> <th align="center">数量</th> <th align="right">单价</th> <th align="right">小计</th> <th></th> </tr> </thead> <tbody> @foreach (var line in Model.Cart.Lines) { <tr> <td align="left">@line.Product.Name</td> <td align="center">@line.Quantity</td> <td align="right">@line.Product.Price.ToString("c")</td> <td align="right">@((line.Quantity * line.Product.Price).ToString("c"))</td> <td> @using (Html.BeginForm("RemoveFromCart", "Cart")) { @Html.Hidden("Id", line.Product.Id) @Html.HiddenFor(x => x.ReturnUrl) <input class="actionButtons" type="submit" value="移除"/> } </td> </tr> } </tbody> <tfoot> <tr> <td colspan="3" align="right">总计：</td> <td align="right">@Model.Cart.ComputeTotalValue().ToString("c")</td> </tr> </tfoot> </table> <p align="left" class="actionButtons" style="width: 100%;clear: both"> <a href="@Model.ReturnUrl">继续购物</a> @Html.ActionLink("结账","CheckOut") </p>
点击结账，跳转到一个视图页面，填写必要的联系方式等信息，其对应的模型为：
using System.ComponentModel.DataAnnotations; namespace MySportsStore.Model { public class ShippingDetail { [Required(ErrorMessage = "必填")] [Display(Name = "姓名")] public string Name { get; set; } [Required(ErrorMessage = "必填")] [Display(Name = "地址")] public string Line { get; set; } } }
订单提交页Cart/CheckOUt.cshtml：
@model MySportsStore.Model.ShippingDetail @{ ViewBag.Title = "CheckOut"; Layout = "~/Views/Shared/_Layout.cshtml"; } <h2>填写地址等信息</h2> @using (Html.BeginForm()) { @Html.LabelFor(m => m.Name) @Html.EditorFor(m => m.Name) @Html.ValidationMessageFor(m => m.Name) <br/><br/> @Html.LabelFor(m => m.Line) @Html.EditorFor(m => m.Line) @Html.ValidationMessageFor(m => m.Line) <p align="center"> <input class="actionButtons" type="submit" value="提交订单"/> </p> }
运行：
在为Cart控制器添加处理订单的方法之前，我们首先定义一个处理订单的接口：
using MySportsStore.Model; using MySportsStore.WebUI.Models; namespace MySportsStore.WebUI.Abstract { public interface IOrderProcessor { void ProcessOrder(Cart cart, ShippingDetail shippingDetail); } }
假设，我们希望在接到订单时发邮件给管理员，创建一个实现IOrderProcessor的类：
using System.Net; using System.Net.Mail; using System.Text; using MySportsStore.WebUI.Abstract; namespace MySportsStore.WebUI.Concrete { public class EmailOrderProcessor : IOrderProcessor { public void ProcessOrder(Models.Cart cart, Model.ShippingDetail shippingDetail) { MailMessage mailMsg = new MailMessage(); mailMsg.From = new MailAddress("qdjjx9441@sina.com"); mailMsg.To.Add(new MailAddress("764190362@qq.com")); mailMsg.Subject = "新订单"; //邮件内容主体 StringBuilder body = new StringBuilder(); body.AppendLine("接收到一个新订单："); body.AppendLine("<br />"); body.AppendLine("订购商品包括："); body.AppendLine("<br />"); foreach (var line in cart.Lines) { var subTotal = line.Product.Price * line.Quantity; body.AppendFormat("{0}*{1}(小计：{2:c})", line.Quantity, line.Product.Name, subTotal); body.AppendLine("<br />"); } body.AppendFormat("总计:{0:c}", cart.ComputeTotalValue()); body.AppendLine("<br />"); body.AppendLine("收货人信息："); body.AppendLine(shippingDetail.Name); body.AppendLine(shippingDetail.Line); body.AppendLine("<br />"); mailMsg.Body = body.ToString(); mailMsg.IsBodyHtml = true; SmtpClient smtpClient = new SmtpClient("smtp.sina.com"); smtpClient.Credentials = new NetworkCredential("some username", "some password"); smtpClient.Send(mailMsg); } } }
把接口IOrderProcessor和实现类EmailOrderProcessor交给Ninject来实现，以便依赖注入：
private void AddBindings() { ninjectKernel.Bind<IProductService>().To<ProductService>(); ninjectKernel.Bind<IOrderProcessor>().To<EmailOrderProcessor>(); }
现在可以在Cart控制器中添加处理订单的逻辑：
using System.Linq; using System.Web.Mvc; using MySportsStore.IBLL; using MySportsStore.Model; using MySportsStore.WebUI.Abstract; using MySportsStore.WebUI.Models; using Ninject; namespace MySportsStore.WebUI.Controllers { public class CartController : BaseController { [Inject] public IProductService ProductService { get; set; } [Inject] public IOrderProcessor OrderProcessor { get; set; } public CartController() { this.AddDisposableObject(ProductService); this.AddDisposableObject(OrderProcessor); } public ViewResult CheckOut() { return View(new ShippingDetail()); } [HttpPost] public ViewResult CheckOut(Cart cart, ShippingDetail shippingDetail) { if (cart.Lines.Count() == 0) { ModelState.AddModelError("","购物车为空"); } if (ModelState.IsValid) { OrderProcessor.ProcessOrder(cart, shippingDetail); cart.Clear(); return View("Completed"); } else { return View(shippingDetail); } } ...... } }
订单提交成功后，显示Cart/Completed.cshtml视图：
@{ ViewBag.Title = "Completed"; Layout = "~/Views/Shared/_Layout.cshtml"; } <h2>谢谢惠顾~~</h2>
运行，点击提交显示：
管理员收到邮件：
至此，订单处理结束。
